On January 23, we started the day by going ziplining.
When we finished, we drove up to Haleakala
On January 24, we booked a SNUBA excursion. This is a cross between snorkeling and scuba diving, since we were able to completely submerge, but were tethered to a boat with air tanks.
During the remaining two days (Jan 25-26) we explored on our own.
We also visited the Maui Ocean Center.
